NELSON SIGLIN, OF AURELIA, IOWA.

Grampians-Madame non BAND-comma Knives.

Application filed October 29, 1908.

concern: Be it known that I, NELSON SIGLIN, a citizen of the United States, residing at Aurelia, in the county of Cherokee and State of Iowa, have invented a certain new and useful Grinding-Machine for Band-Cutter Knives, of which the following is a specification. 2

The object of my invention is to provide a grinding machine of simple, durable and inexpensive construction, and of few parts, especially designed for use in grindmg the knives of a band cutter and selfefeeding device for threshing machines. to be understood that knives quickly and easily be detached from the rest of the machinery, and hence it is desirable that the means for sharpening them be so arranged that the grinding machine may be conveniently and easily operated by hand, and the grinder applied to the band cutter knives while they are still in position in a machine of the class set forth.

My object therefore is to provide a machine of this class of compact structure, capable of being placed in various positions, and being readily and easily carried and contained in a small space.

My invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claim and illustrated in the accompanying drawings, in wh' Figure 1 is a side elevation of the standard and gearing with a small portion of the flexible shaft attached to the frame. Fig. 2 shows a top or plan view of same. Fig. 3 shows an enlarged sectional view on the line 33 of Fig. 1, and-Fig. 4 shows a detail sectional view of the flexible shaft.

Referring to the accompanying drawings, 1 have used the reference numeral 10 to indicate the standard of the device, which standard is preferably made of a single piece of tubing or pipe, and is provided with'legs 11 at its lower end. Its upper end is slotted at 12, as shown in Fig. 3, and a clip 13 is extended around it and provided with an adjusting bolt 14 in its end, by which the parts of. the standard between ressed inwardly.

The supports for the gearing devices are preferably made of two castings, the first one comprising an upright mem er 15 fitted into the upper end of the tubular standard 10,

and having an arm 16 extended upwardly and outwardly from it, and also having an integral handle 17 at its top extended up wardly, and a transverse bearing 18, and

another transverse bearing 19 at right angles to the bearing 18. All of the parts 15, 16, 17, 18, and 19 are cast complete in one piece. The other part of the gearing supporting 1, frame comprises a central cross piece 20, two arms 21 having bearings 22 at their ends, and bearings 23 at their other ends. The cross piece20 is designed to rest on and be supported by the arm 16. g

Mounted within the bearing 19 is a shaft 24 having a handle 25 thereon, and a large beveled pinion 26. In oneend of the bearing 18 is a pin 27 having the bearing 22 mounted thereon, and on the other end 0 the bearing 18 is a shaft 28 extended through the bearing 22, and fixed in position in the bearing 18.

Rotatably mounted u on the shaft 28 is a sleeve 29 having a smal beveled pinion 3O thereon to mesh with the pinion 26, and a cog wheel 31. Rotatably mounted in the bearings 23 is a shaft 32 having on one end a pinion 33 in mesh with the pinion 31, and on its other end, a small beveled pinion 34. A sleeve 35 surrounds the shaft 32 and is extended through the bearings 33 and on the end of said sleeve 35 adjacent to the pinion 34 is a hanger 36 fixed to the sleeve 35. This hanger supports a short rotatable shaft 37 provided with a beveled Cpinion 38 in mesh with the pinion 34. onnected with the shaft 37 is a flexible shaft 39 covered by a flexible hose 40. The other end of the flexible shaft 39 is attached to a short shaft 41 and connected with the short shaft 41 is a grinding wheel 42. A sleeve 43 is rotatably mounted upon the short shaft 41, to thereby provide a convenient handle.

In ractical use, the operator grasps the handle 17 and moves the grinding machine to the desired position adjacent to the band outter knives. The frame may be conveniently and easily held either in an upright position, or at any angle by means of said handle. Then the operator turns the crank 25, which results in imparting a rotary motion at a greatly increased speed; to the grinding wheel.

The part 15 may be rotated upon the standard, and the bracket 36 may be rotated upon the sleeve 35 in a plane opposite tated, so that a universal movement of the with each other and rotatably mounted on short shaft 37 is thereby permitted.

arranging the parts as shown, it is obvious that the machinery is very compact, and occupies a small space, and yet the speed of rotation is greatly increased from the crank 25 to the grinding wheel.

All of the parts are readily detachable and replaceable, and the entire device may be quickly and easily assembled so that it is inexpensive in construction, and it is also strong and durable in operation.

claim as my invention:
